Proposing new rule 'Remove unnecessary suppression' same as IDE0079

[maettu-this]

IDE0079: Remove unnecessary suppression works fine for IDE.... rules, but not for other analyzers. Proposing to add a new IDISP.... rule 'Remove unnecessary suppression'.

Motivation: Clean code, minimum of suppressions.

Such new rule could be considered too intrusive. Still, it could be added as "opt-in" rule, i.e. keep disabled by default at first and only later default to enbled once the new rule has been adopted by the majority of users.

In the meantime I got told at DotNetAnalyzers/StyleCopAnalyzers#3685 that IDE0079 is supposed to include other analyzers but doesn’t fully work yet. If IDE0079 indeed will cover the IDisposableAnalyzers, this proposal would be obsolete.

Feel free to keep open until IDE0079 got fixed, or already close it now.
